My battery came in Friday, also PMd Lumintop. I didnt take any initial reading before or after it charged but it took about three hours on the USB Charger . Its basically a Panasonic NCR18650B protected button top that has had a USB port built in. I included a few low resolution pictures, sorry but my tablet has a horrible camera. I had no problem installing battery into an Ultrafire 502B , Solarforce L2 and L2T. The length was the only difference between the two batteries. the Lumintop being 1mm longer. I didnt try a technical review because HKJ has already done that with the Panasonic Test / Review: Panasonic NCR18650B Protected 3400mAh (Green) and I would not be able replicate his test conditions. Thanks HKJ . The USB port seems functional on the other hand practical is a matter of perspective.
Initial packaging. note line top left corner was me starting to cut open package before pictures taken.
